九人（Y。Taniguchi，H. Suto，T.长谷川湾Wakamatsu，M. Tanaka，K. Iwasawa，F.佐藤，澳-地Sofue和K. Ogura）被委托进行光学、红外和射电区域各种波长的天文观测。目标是：1）星际介质（Suto，Tanaka和Ojura）2）星系（Taniguchi，Iwasawa，and Sfue），和3）falanus集群（长谷川、若松）。他们的活动致力于国家或地区是冒纳肯（JCMT和UKIRT）、美国格林班克和德国波恩以及智利和南非的托洛洛山、拉西拉。1）Suto在J、H和K波段对15个恒星形成区进行了红外成像。在红外源IRAS 11072-7727周围探测到一个显著的复杂星云。Ogura用SEST（瑞典-欧洲南方天文台）望远镜观测了他自己发现的赫比格-哈罗天体HH 135/136，CO谱线为1.3和1.4毫米。一个高速的分子外流被检测到在 关于我们 12 CO（J=2-1）在1.3mm处有一条发射线，而13 CO（J=2-1）则显示出一个致密的分子核，围绕着这两个HH天体。在调查中，他描绘了包裹着复合体的中性氢云，在银经110度，银纬3度处有一直径为10度的壳层结构。2）Taniguchi发现星暴星系的环核云温度明显高于我们星系的正常分子云温度。Tanaka发现Seyfert/cD星系NGC 1275的光谱分辨率为30 km/s，岩泽用CTIO 1.5m望远镜获得了17个星系光学区的光谱。他在IRAS 18325 -5926中发现了一个典型的塞弗特2光谱，Ginga根据X射线观测将其命名为塞弗特1。他还在Tololo 0109-38的Fell lambda 4570处发现了一个隆起，以及一个与Mkn 603有关的蓝色致密矮星系。Sofue试图使用德国的波恩100米射电望远镜探测三个红移为2至3的类星体或相关天体的CO吸收线，3）长谷川用RPCS低信噪比测量了蛇夫座星系团中50个星系的后退速度，南非1.9米望远镜的高分辨率光谱仪。他发现了新的星系团。结合他和他的同事以前发现的星系团，他得出结论，这些星系团形成了一个超星系团，在超星系团和我们之间存在一个巨大的空洞。若松用智利CTIO 1.5米望远镜的卡塞格伦光谱仪对上述区域进行了广泛的光谱调查。上述超星系团向武仙座星系团延伸，呈现出100 Mpc的“墙”结构。因此，在该计划中开展了包括星际介质、星系活动和星系团结构在内的多个领域的研究。一批高水平的论文已经发表或正在编写中。如果没有位于世界上最好的地点的望远镜，这些成功是无法实现的。本研究计划已实现了大部分计划进度。少

Nine persons ( Y. Taniguchi, H. Suto, T. Hasegawa, K. Wakamatsu, M. Tanaka, K. Iwasawa, F. Sato, Y. Sofue, and K. Ogura ) were delegated for astronomical observations with various wavelengths in the optical, infrared and radio regions.The objectives are 1) interstellar medium ( Suto, Tanaka, and Ojura ) 2) galaxies ( Taniguchi, Iwasawa, and Sfue ), and 3) clusters of falaxies ( Hasegawa, Wkamatsu ).The countries or areas where their activities were devoted are Mauna Ken (JCMT and UKIRT), Greenbank, USA, and Bonn, Germany, in the northern hemisphere and Cerro Tololo, La Silla in Chile and South Africa.1)Suto made infrared imaging for 15 star-forming regions at J, H, and K bands. A remarkable complex of nebulosities was detected around infrared source IRAS 11072-7727. Ogura carried out an observation of Herbig-Haro objects HH135/136, which had been discovered by himself, with CO lines at 1.3 and 1.4 mm at SEST (Swedish-ESO) telescope. A high-velocity molecular outflow was detected in the … More 12CO(J=2-1) emission line at 1.3mm, while a dense molecular core encompassing thetwo HH objects was revealed in the 13CO(J=2-1).Sato made an extensive survey of a Cepheus-Cassiopeia complex region with neutral hydrogen at a wavelength of 21cm with NRAO Greenbank 43m radio telescope, USA. In the survey, he delineated the neutral hydrogen cloud enveloping the complex, and a shell structure with a diameter of 10ﾟ degrees locating at a galactic longitude 110ﾟ and a galactic latitude 3ﾟ .2)Taniguchi found that temperature of circumnuclear clouds in the star-burst galaxies is significantly higher than that of normal molecular clouds in our galaxies.Tanaka detected a broad width of H2 molecular line for a Seyfert/cD galaxy, NGC1275 with a spectral resolution of 30 km/s.Iwasawa obtained spectra in the optical regions of 17 galaxies with CTIO 1.5m telescope. He found a spectrum exhibiting the typical Seyfert 2 in IRAS18325-5926, which was designated to Seyfert 1 from the X-ray observations by Ginga. He also detected a bump at Fell lambda 4570 in Tololo 0109-38, and a blue compact dwarf galaxy associated with Mkn603.Sofue tried to detect the CO absorption line toward three quasars or related objects with the redshifts of 2 to 3, using the Bonn 100 m radio telescope in Germany, but failed to detect it with sufficient signal-to-noise ratios.3)Hasegawa made a measurement of recession velocities for 50 galaxies in the cluster of galaxies in Ophiuchi constellation using RPCS low-resolution spectrometer at 1.9m telescope in South Africa. He discovered new clusters of galaxies. Combining the clusters of galaxies previously discovered by himself and his colleagues, he concluded that these clusters of galaxies form a supercluster of galaxies, and there lies a huge void between the supercluster and us.Wakamatsu carried out an extensive spectroscopic survey for the above region with the Cassegrain spectrometer at CTIO 1.5m telescope, Chile. The above super-cluster extending toward Hercules cluster of galaxies shows 'Wall' structure with an extent of 100 Mpc.Thus, a various field of researches were carried out in this program, covering interstellar medium, activities in the galaxies, and structures of the clusters of galaxies. A number of papers with high levels were published or are in preparation. Without the access to the telescopes located at the excellent sites in the world, these success could not be attained. Most of the planned schedules have been achieved in this research program. Less
